+**Dockerfile and docker-compose**
+
+You can use Docker to build your own container based on Alpine Linux. This image configures SSHD to be run by user root and GitPrep to be run by user gitprep.
+
+    docker build ./deploy -t jndeverteuil/gitprep:latest
+
+With that build, you can start a service with docker-compose:
+
+    version: "3"
+
+    services:
+    gitprep:
+        image: jndeverteuil/gitprep:latest
+        container_name: gitprep
+        hostname: gitprep
+        restart: always
+        ports:
+        - "10020:10020"
+        - "0.0.0.0:2222:22"
+        volumes:
+        - gitprep:/home/gitprep
+        - sshd:/etc/ssh
